Oh, nothing beats the joy of seeing your miles add up !
Even if you don’t travel a lot , being registered to a rewards program such as AirFrance’s FlyingBlue or Lufthansa’s Miles & More is one of the first things to do ! The trick is to have one card per airline network. There are two of them: StarAlliance and SkyTeam. Although the best thing is to always travel with a single airline or network (that way you can get more miles), sometimes it is not possible. Maybe the cheapest airfare is with StarAlliance , or viceversa.
The point is not to lose miles ! Remember : everything adds up !
You can use your miles for renting cars, hotels, you can even buy wine with them. The point is to take advantage of the airline’s programs no matter where you go.
